erasable paper from Xerox is revolutionary

The experimental printing technology, a collaboration between the Photocopier pioneer Xerox (Research Centre of Canada) and PARC (Palo Alto Research Center Inc.), could replace printed pages that are used for just a brief time before being discarded. Xerox Corporation scientists have invented a way to make prints whose images last only a day, so that the paper can be used again and again.
